LEAF-HOLDER FOR TRANSFER-BINDERS.

SPECIFICATION forming part of Letters Patent No. 721,100, dated February 17, 1903.

Application filed June 14, 1902.

To all whom it may concern:

Be it known that I, ISAAC H. SISSON, a citizen of the United States of America, and a resident of the city and countyof Providence, in

5 the State of Rhode Island, have invented certain new and useful'lmprove'ments in Leaf- Holders for Transfer-Binders,of which the following is a specification.

My invention relatesto transfer-binders,

[ so called, but more especially to the novel construction of the leaf-holders or extensible pins adapted to receive thelooseleaves from the temporary hinder or ledger; and it consists, essentially, in the combination,with the laterally-separable front and back 7 or cover members, of a short tubular or hollow stud rigidly secured to one of said members and passing loosely through the other member and a removable pin fitting the bore of said hollow stud or tube havingan integral shouldered portion registering with its exterior diameter and a looking or securing device for the pin arranged whereby upon inserting the latter into the tube to its limitand turning it (the pin) axially-say one-half a revolution the stud and pin then become practically'one and constitute a rigid holder for, the leaves. The removable cover member,slidably mounted on the holde r-pins,may be pressed toward 0 the fellow member the desired distance and secured in position in any well-known or suitable manner.

By means of this invention the permanent file or transfer-binder is capable of being readily adjusted to any desired width or thicknessshort of its maximum to receive the loose leaves transferred thereto from the ledger or transfer-binder.

In the accompanying sheet of drawings,

Figure 1-is a horizontal sectional view, en-

larged, taken substantially on line :0 x of Fig. 8, the leaves being omitted. Fig. 2 is a transverse section taken on line 2 2 of Fig. 1. Figs. 3, 4, and 5 represent a series. of insertible locking-pins adapted to be used in combination with the tubular stud, which latter is rigidly secured to one of the cover members of the binder, thereby adapting the latter to be adjusted to different thicknesses as de- Serial No. 111,641. (No model.)

sired. Fig. 6 is an inverted horizontal section taken on line 6 .6 of Fig. 1, showing the pin in its locked position. Fig. 7 'is a sectional view similar to Fig. l, but showing the device adapted and adjusted to the shorter pin. Fig. 8 is a plan view, in reduced scale, of the front frame member, showinga device for locking or adjustably securing the frame to the leaf-holders, the cover-plate being removed; and Fig. 9 is a perspective view of a transfer-binder complete as in use and embodying my improvement.

In the drawings, a and b design ate the front and back metallic frame members of the covers m provided with two pins or leafholders adapted to receive leaves 10. (See Fig. 9, in which isshown the transfer or permanent file A complete.) The saidback member b has rigidly secured thereto at "or near each end thereof .-a hollow stud i, the same being arranged perpendicular to the plane of the face of the member I), as clearly shown. The loweror fixed end of the stud has a short" pin 0 passing transversely therethrough and extending partly into the bore ofthe stud." (See Figs. 1 and 6.) The other or front member a of the frame has a hole formed therein, the same registering with and adapted to slidably receive the stud. The member a is provided with a longitudinally-movable bar cor other suitable locking or clamping device adapted to frictionally engage the side of the stud, thereby when adjusted maintaining the frame in position against lateral movement. Thebar is kept in place by a removable plate (1. I make no claim'herewith, however, to any clamping device, since the same forms no part of my present-application for patent.

I may state that the bars c,slidably mounted in the frame a, may be actuated by means substantially as indicated in reduced scalein Fig. 8that is to say, the inner ends ofthe bars are adapted to engage the beveled sides of a nut a? capable of moving perpendicularly a short distance through the medium of a revoluble screw 0, in turn actuated by a suitable key inserted in the keyhole v, the latter being indicated in Fig. 9. Now upon turning the screw the nut is forced endwise, thereby causing the beveled sides thereof to simultaneously press the bars apart a corresponding distance to frictionally engage the sides of the shouldered portion h of the two studs or pins. (See also Fig. 1.) This device, however, is more clearly set forth and claimed in a concurrent application for Letters Patent filed by me, Serial No. 111,639.

The other part or member comprising the leaf-holder consists of the pin h, adapted to be inserted into and removably secured to the stud 2'. Its inner or lower end is flattened on one side (see '12) and also provided with a peripheral groove or recess n, arranged to receive and register with the said fixed pin 0 of the stud. The removable pin 72. has a shouldered portion h, whose diameter is the same as that of the stud and terminates in a suitably-shaped or rounded head 71 as clearly shown. The face of said shoulder is adapted to bear snugly against the outer end of the stud, the relation of the pin 0 to the groove it being such that they register with each other when the holder-pin h is inserted to its limit or arrested by its shoulder h. In inserting the pin hit is first turned until the flat side 92' thereof lies contiguous to the fixed pin 0, followed by turning it, say, one-halfa revolution, thereby locking the pin h in position against accidental removal. A reversal of the operation permits the pin to be readily withdrawn.

By simply providing the binder with a series of locking-pins h, having shouldered portions h, varying in length the same binder is capable of being employed for holding a greater orless number of leaves p,as required, or, in other words, the binder may be readily converted from a comparatively thin file into one having a much greater thickness, limited only by the length of the shouldered portion h of the locking-pin. In this device the back member I), with its tubular studs 2' fixed therein, and also the front frame a remain unchanged, the only change required to convert the binder from the minimum to the maximum thickness or capacity being to substitute a longer pin h for the shorter one, as before stated.

In Fig. 9 I have indicated a temporary binder complete, provided with front and rear covers and two leaf-holding pins, the head h and a part of the shouldered portion h of said pins being represented. The front or slidable frame a may beheld in position by means of endwise'slidable bars 0, adapted to bear against the pins, Fig. 1, and capable of being actuated in any well-known or suitable manner by means of a key inserted in the keyhole 1). These features, however, form no part of the presentinvention, as before stated.

I do not claim as my invention pins or postsections varying in length arranged to be screwed into and registering with fellow posts secured to the lower cover-section.

I claim as my invention I 1. In a transfer-binder or file for loose leaves, the combination with front and rear frame or cover members, of a plurality of hollow studs rigidly secured to and extending perpendicularly to the plane or face of one of said frame members, the bore or interior of the lower end of each stud having a fixed locking member, removable locking-pins each having its outer diameter the same as that of said studs, thereby practically forming when in use an extension or continuation of the latter and being uniform in diameter throughout, the lower portion of said locking-pin being reduced in size to fit the bore of the studs, and having the bottom end of said reduced portion of the pin cut away or flattened and adapted to interlock with the said interior locking member of the stud upon turning the pin a partial revolution, substantially as hereinbefore described and for the purpose set forth.

2. The improved extensible leaf-holder for binders, substantially as hereinbefore described, the same comprising a plurality of 0 tubular studs 11 uniform in length perma-. nently secured to one of the frame or cover members of the hinder, the interior of each stud having a fixed pin or looking member, and a series of interchangeable locking-pins 95 having thelower or outer end portions thereof uniform in diameter and length, said end portions being cut away or flattened and adapted to interlock with the said interior locking member of the stud upon turning the pin a IOO partial revolution, and further having the diameter of the upper or other portion of said series of locking-pins the same as the outer diameter of the studs by varying in length, substantially as set forth.

3. The improved leaf-holder for binders, substantially as hereinbefore described, the same comprisinga hollow stud i, permanently secured to one of the frame or cover members, having a fixedpin 0 mounted in one end therer to of and extending into and transversely of the bore of the stud, and a shouldered lockingpin h havinga flattened portion, 91., at its inner end and also provided with a peripheral groove n adapted to engage said pin 0, the n 5 said stud and locking-pin capable of passing transversely through the other frame or cover member, all constructed, arranged and adapted for operation substantially as described.
